摘要： PROBLEM TO BE SOLVED: To solve such a problem that, in a conventional energy saving service, a user and an energy saving service provider cannot necessarily receive merits of energy saving because initial investment by a contractor (for example, the user of an electric power facility) is necessary and the energy saving service provider guarantees a target value of energy saving to the user.SOLUTION: For a facility which is owned by a user who desires energy saving and has the target load facility, present power consumption is measured. A service provider installs an inverter, or an inverter and a motor or the like in the target load facility, performs motor speed control by the inverter, obtains merit charge based on difference between the present power consumption and power consumption with use of the inverter, and distributes the merit charge by reflecting the merit charge to content previously decided between the user and the service provider.

摘要： PROBLEM TO BE SOLVED: To make it possible to accelerate an induction motor with good efficiency with the rotational angular velocity of an induction motor coincident quickly with the angular velocity command of an inverter by a method, wherein, when a torque component becomes smaller than a synchronous turning-on permission current, a mode is changed over to an acceleration mode and a steady operation in a constant-speed mode is started when the torque component reaches a rated current. SOLUTION: A mode comparator 11-11 outputs an angular velocity instruction ω1. At this time, the angular velocity command ω1 contains a first-order lag element so as to become small, and it is brought close to an angular velocity at which an induction motor is turned. That is to say, the angular velocity command ω1 is brought close, from a rated angular velocity ωdef, to an angular velocity at which a rotor at the induction motor is turned, and it coincides nearly with the angular velocity. Then, the torque current component of the induction motor is reduced. Then, at a point of time when the torque current component becomes smaller than a synchronous turning-on permission current, a mode is changed over to an acceleration mode. Then, when a transient angular velocity ωtrn which is computed by a synchronous turning-on computing unit 11-13 and which is given to the induction motor is raised up to the rated angular velocity ωdef, the mode enters a steady mode.

摘要： PROBLEM TO BE SOLVED: To start in a short time, when a motor is starting up and restarting from instantaneous power failure, and prevent the motor from generating overcurrent for a stable operation. SOLUTION: A control part 7 of an induction motor is provided with a command part 9, an acceleration/deceleration control part 10, a current angular velocity control part 14, a current control discriminating circuit 15, a switching device 16, an angular velocity command part 17, an instantaneous stop acceleration/deceleration control 30, an instantaneous stop setting current control 32, an exciting current variable speed circuit 31, and a feedback current selective circuit 33, stores a value of output angular velocity prior to instantaneous stop to an output angular velocity storage circuit when power failure occurs instantaneously. When is restarts from instantaneous stop, verifies that the induction voltage of a motor became equal to a specified value or lower, takes the angular velocity stored in the output angular velocity as an initial value to return to the output angular velocity, and compares the feedback torque current of the larger existing current and the set current for current angular velocity control, thereby enables restarting from instantaneous stop extending across the four quadrants of the motor.
